[7/31/2018] Rick Foster and Laura Ingwell, Purdue University, discuss why our insecticides might not be perfoming the way we are used to.

[7/27/2018] Since our last report (July 11th), and likely due to the recent heat in mid-July, SWD adults at most trap locations, actually declined, to low to moderate levels in the metro-area trap network. It is now known that SWD does not like the heat during the day (e.g., >85F), and will often “hunker down” at the base of thick canopies (e.g., raspberry, blueberry), or will move to nearby wooded areas to seek shade during the day – especially when the forest shade is adjacent to fruit production fields. 

[7/12/2018] Major concerns and reports of JB damage are now common on raspberry (summer, fall), blueberry and wine grapes. 

[7/11/2018] This month's episodes of "What's Killing My Kale?" is all about plant diseases. 

[7/11/2018] SWD adults, at most trap locations, reflected substantial population growth as of July 3rd. It’s clear that SWD did not take any time off for July 4th and has continued its population growth this week. 

[7/5/2018] SWD adults, at most trap locations, reflected substantial population growth as of July 3rd. With three locations reporting so far, reflecting a range of fruit crops and fruit maturity, we are updating selected locations here.

[6/28/2018] As noted last week, the first SWD adults, collected in Scentry SWD traps this year were first detected June 8-9th, at Rosemount, UMORE Park (Dakota Co.) and near strawberries in SE Minn. (Houston Co.). Since then, as of Wednesday last week, all trap locations in the Metro area were positive, albeit at low levels, with adult numbers ranging from 1-6 SWD/trap. 

[6/22/2018] The first SWD adult flies, detected in Scentry-baited traps, were collected June 8th, at Rosemount (UMORE Park, Dakota Co.), and June 9th near Mabel (Houston Co.) – both with just 1 adult per trap/week.

[6/7/2018] Researchers from 12 different institutions have published new managment recommendations for SWD in organic berry crops.
